Not sure what you mean by 'independent' - DF is a story publication officially recognized by Capcom, announced and advertized on DMC4 off.site (as 'complete novellization') and later on HDC off.site along with novels 1,2, manga 3 and anime. Therefore, anything written in it is official and needs no further reconfirmation (but it can be retconned ofc - as anything else, 17 so far wasn't). About 'rest of the series' - most of it since 3 was written by Bingo. And discrepancies with DF are miniscule if you compare it to those of, say, DMC3 with 1, but all of them is still in the same continuity.
